Abstract

A mix for forming a magnesite-carbon refractory shape comprising from about 70 to 97 wt.% deadburned magnesite and about 3 to 30 wt.% flake graphite, and for each 100 wt.% of said magnesite and graphite, from about 1.5 to 6 wt.% of a carbon-containing bonding agent; said graphite containing from 90 to 99 wt.% carbon and having a lime/silica ratio greater than 0.2 in its ash and said magnesite containing greater than 95 wt.% magnesia, and the resultant magnesite-carbon refractory shapes and liners for metal processing equipment made from such shapes and the method of increasing the life of liners for such equipment. <IMAGE>
